Since you know about the E46 cooling system life cycle, it's now a matter of risk management. When you become worried about the cooling system every time you start the car, it's time to replace it.

Really only when I "worry" about it? I could've sworn I saw a scheduling. I mean i've been checking it every 6months-year to make sure its doing well. I guess I'll start my own preventive maintenance schedule for it

There's much debate on the topic. Some say 30,000 miles, other say 60,000 miles. I would lean more towards 60,000 miles, but remember, that's my opinion. There's no "right" answer to this. It's like the oil change interval.

You're giving him **** for making another thread about the cooling system yet in this one 4 people are asking question that have been addressed hundreds of times in the other threads?

Agree with Mango or not, but stop your needless bickering back and forth like a bunch if 14 year old girls making fun of Suzy small boobs in the locker room and accept this thread (and Mangos advise) for what it is: a reminder to watch for potential issues and fix them BEFORE they cause permanent damage.

Jeez, this forum is filled with some of the most immature babies crying look at me I've ever seen!!!

Every 60,000 miles: water pump, thermostat, plastic thermostat housing if so equipped
(or replace it once with the aftermarket aluminum thermostat housing)

Every 90,000 miles: radiator, expansion tank, fan and fan clutch if so equipped (for cars
you're going to keep forever, consider using the all-aluminum radiator and expansion
tank from www.zionsvilleautosport.com and you won't have to do it again at 180,000)

Thanks for the information, I might be still on my original radiator. May need replacement soon

When I was driving with my dad in the E39, the ET blew up. This was at about 50K. There was plenty of time to drop it into neutral and shut off the engine. Why is everybody overdramatizing this? Your engine will not be damaged instantaneously.

Not trying to cause trouble, just speaking from a first hand account.

No you are right. You have plenty of time if you notice your needle is out of the proper range. Unfortunately, a lot of people don't seem to notice the needle until it is in the red zone with the light on. Then you wonder how long it's been there. Apparently it doesn't take long to blow out the head gasket once the needle reaches the red zone (that's what I've heard).

To solve that problem, you can buy the Coolant Snitch. Is it worth the $90? I don't know, but it could be.

As WDE said, not everyone is that lucky. That's evident by all the threads we get on warped headgaskets. Even if you did know and had the "perfect" plan of attack in case of a failure, it's nice to even not have that failure in the first place. That will cost you extra time and money you'll never get back.

As far as the color of my skin, who cares? Why anyone would even bring that up blows my mind. If you're genuinely interested, you'll know when you meet me. If you want to know just to have an angle of attack or exploitation of some sort to suit your anti-mango agenda, forget about it. It's silly

Calling you "asian" or calling anyone by there race is not racist and if it is I'd like to state I've been called "jewish" by fellow forum members. I'm proud of it, and saw no "racism" in it. It's people like you that will never let the racism debate die.

You were wrong in the tailgating thread, and now you're trying to win every thread. Just stop.

Calling someone "Asian" if not racist, but if it followed by some racist statements then it is racist, I didn't read Hallisters post so I can't really comment on it but I assume he's not for good fate.

Anyway, by law racist or race discrimination is against the law.

He has been trolling me in this and other threads because I disagreed with him in another thread a couple weeks back. Calling someone Asian in and of itself is not racist, but in this case the intent is when you're trying to use it as an attack because your argument isn't going your way. That's clearly evident in that it was brought up in a totally car-related (cooling) thread.

Being racist is not illegal. Practicing discrimination when it comes to businesses and the like is illegal though. That's about it. It's legal to go around yelling about how much you hate *insert minority racial slur*, but you might get your ass beat.

I listened to Mango once, and I replaced my cooling system because I was leaking pretty badly. Everything that was listed in his "sig" was replaced, but I ended up still leaking.

Pissed off and annoyed that I wasted all that money on a problem still not fixed, I took it to a Master Mechanic and he laughed and said that my coolant hose from the expansion tank (PN: 11531436410) was leaking, more specifically "mushrooming". It was a $25.00 part to replace, and it fixed my leaking issue complete.

This list is not "whole".

My two cents on the subject, when new members post in here regarding cooling system problems next time, Mangno don't just copy and paste "See sig, do all" because you really don't know.

You took your car to a "Master Mechanic" because you couldn't find a bad hose!!
